And thus We have sent it down as an Arabic Qur'an and (20:113)

﴿وَكَذَٰلِكَ أَنزَلْنَاهُ قُرْآنًا عَرَبِيًّا وَصَرَّفْنَا فِيهِ مِنَ الْوَعِيدِ لَعَلَّهُمْ يَتَّقُونَ أَوْ يُحْدِثُ لَهُمْ ذِكْرًا﴾
[ طه: 113]

20:113 And thus We have sent it down as an Arabic Qur'an and have diversified therein the warnings that perhaps they will avoid [sin] or it would cause them remembrance.

I have revealed the Qur’ān in clear Arabic just as I revealed the stories of the previous prophets, and I have explained in it different warnings of threat and fear, in the hope they will fear Allah or that the admonition of the Qur’ān will cause them to reflect.

And thus We have sent it down as a Quran in Arabic, and have explained therein in detail the warnings, in order that they may fear Allah, or that it may cause them to have a lesson from it (or to have the honour for believing and acting on its teachings).
